Since the function y = sin(θ) is equal to 0 at θ = nπ where n is an integer, we need to find the values of θ for which 4nπ < θ < 7π.
These values fall into the intervals of:
- 5π < θ < 6π
- 6π < θ < 7π
Therefore, the values of θ for which y = sin(θ) is equal to 0 when 4nπ < θ < 7π are θ = 5π and θ = 6π.
The correct answer is B) θ = 5π, 6π.
